Abstract

A membrane-electrode unit (1) with integrated sealing edge for a polymer electrolyte membrane fuel cell having a polymer electrolyte membrane (2), an anode (3) arranged on one surface of the membrane and a cathode (4) arranged on the other surface of the membrane, is made from a layer material of anode material, cathode material and polymer electrolyte membrane material disposed therebetween, from which pieces of suitable size are severed, with the membrane, in the severed pieces, being covered completely by the electrodes on both of its sides. On the periphery of said piece, a sealing edge (5) is formed such that the sealing edge (5) penetrates an edge portion (6', 7') of at least one of the electrodes (3, 4) and adheres to the membrane portion adjacent the edge potion and/or the sealing edge adheres to the end faces of at least one of the electrodes and the end faces of the membrane.
